After I turned in 'All Aboard', I went to where the flying warship is supposed to be. General Nazgrim is supposed to be on the warship so I can accept the quest, "Into the Mists" and be able to access MOP content. But when I go to the area, there is no ship, and general Nazgrim falls out of the sky, goes into the ocean, and sinks to the ocean floor. Since I'm underwater, I can't talk to him. Is there a way the moderators and/or GMs can advance me past this bug in the questline?
